9. Which type of bond involves the transfer of one or more electrons from one atom to another, resulting in an attraction between the negatively and positively charged ions? A. hydrogen B. covalent C. ionic D. sigma E metallic

Answer: C. Ionic

Explanation: The transfer of one or more electrons from one atom to another means that certain atoms are "amplified" by negative charge, since the electrons are negative, while the other atoms from which the electrons leave become positive. This means that such atoms become negative and positive ions, causing each other to attract opposite charged ions, creating an ionic bond.
